Application July 25, 1931. Serial No. 553,038 :u claims. (ci. 257-199)My invention belongs to that general class of devices known as coolersor the like and refers more particularly to a simple, inexpensive deviceadapted for use by dairy farmers in removing the animal heat from themilk, preparatory tothe transporting of the same to the dairy or milkcompany. Milk as it cornes trom cow is of body temperature, and it isnecessary that the vfarmer removes the animal 'heat from the rnilk asquickly as possible, as it is desired that the saine be at a temperatureoi approximately 60 when the same reaches the dairy or factory.

It has been generally the practice on a farm to set the can of mill: ina trough of running water which reduces the temperature to a lowerpoint, as the well water is ordinarily of a temperature below 6. Whilethis method of cooling may be satisfactory during e considerable portionof the year, in extremely hot weather it is found that 2@ it will notaccomplish the reduction in temperature which is necessary.

My present device is designed for use by farmers for rapidly cooling oneor several cans of fresh milk, although it will be obvious that thenumber of units which may be provided may be rnore or less unlimited.The invention has among its objects the pro duction of a device ci' thekind described which is simple, inexpensive, sanitary, durable, of lightWeight, emcient and satisfactory for use wherever iound applicable.

it also has as an object, the production oi e. device of the kinddescribed made up' oi units, so that the number of units maybe increasedor decreased so as to accommodate the number oi' cans that it may bedesired to cool.

The invention also has among its objects the production of a devicewhich may be conveniently manipulated or operated to stir or generallyagitate the milk from time to time during the cooling.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from the dis=closure herein given.

To this end my invention consists in the :novel construction,arrangement and combination of parts herein shown and described, andmore particularly pointed out in the claims.

in the drawing,

Fig. l is a plan view oi my improved device applied to a cooling trough;

Fig. 2 is a sectional view through the same, taken substantially on theline-2m3- oi Fig. 1, illustrating three units;

Fig. 3 is a sectional View taken substantially on the line 3-3 of Fig.2; and

Fig. 4 is a sectional view taken substantially on the line 4 4 of Fig.3.

Referring to the drawing, each unit of my improved construction consistsof a coil or loop consisting of the two legs or extensions 1-1, providedwith an intermediate connecting part 2 at the bottom, 'the upper ends3-3 being extended transversely, and of a length to extend to eitherside of the milk can when the device is positioned. The legs are of alength to extend adjacent the bottom of a can and at the top oi the twolegs is a bridge or connecting bar 4 which forms a grip for conveniencein handling the device, eitiier in applying to or removing it irorn thecan, or during the cleansing, and at the same time, rigidly connects thetwo legs togcther and strengthens the unit. A rocking handle 5 may beplaced at the top, if so desired, the purpose of the same being to rockthe unit as set forth hereinafter. One of theextenslons 3 is connectedto a water supply hose 6 by means of a coupling, union or any equivalentmeans. The pipe 6 is connected to a source of water supply, as forexample to the pump 8, only a portion of the pump being shown.

As shown in Fig. 2, the unit described is connected in series with theother units by means of couplings or unions 7, and the last unit isconnected to a discharge conduit 9, which is preferably of some lengthand provided with discharge openings 10. The extreme end oi the pipe 9is closed so that the Water must be discharged through the openings 10.

'I have shown in Figs. 2, 3 and 4i, an agitator '11, which may besecu'red on the unit, the saine being preferably of simple constructionand readily removable, so that it may be taken ori" for cleaning or whenit is not desired to use the same. The device shown consists of a plate11 of the desired size and shape, which is shown provided with asupporting and securing stem i2, which is forked as at 13, so that itmay be detachably secured to the connecting part 2. It is maintained inposition on the legs 1 1 by similar members lei- 14.

I have shown in the drawing in dotted lines, milk cans 15 ofconventional design, into which the milk is usually dumped after milkingfor transporting tothe dairy. I have also illustrated a trough 16 of thedesired size and shape, and made of suitable material, and which isconstructed to contain water. This is shownprovided with a drain pipe17. Heretoiore, cans have been placed in the trough, water beingsupplied from the pump 8, and discharged through the outlet 1'7, thecooling being entirely at thel cooling the exterior of the cans andcarrying of! the heat, and thence discharged. It is preferred to makethe conduits 6 and 9 of rubber hose or other flexible material and tomake 9 of suflicient length so'that it may be extended about the tank todistribute the cold water therein, the extreme free end, as beforementioned, being closed. The device is of lightweight, anda plurality ofunits may be easily handled without effort, either to apply the devicesto the cans or to remove the same therefrom. To remove or apply, thedevice is handled by means of the handle 4, rather than by grasping thelegs, so that'after the device has been sterilized, it may be handledwithout contaminating the loop legs which depend into the t milk.` If itis desired to agitate the milk to any extent, the units may be raisedand lowered in the container or can 15, this being particularlyefficient if the agitator plate 11 is employed..

Where it is not desired to raise and lower the device, it may be rockedin the can by means of the rocking lever 5, the rocking serving also toagitate the milk. In this connection, owing to the ilexible hoseconnectors, considerable movement is permitted, and of course, thecouplings 'I may be so constructed as to prevent sw'lvelling withoutleakage of water. It will be noted by referring particularly to Fig. 2,that if any of the couplings should leak, the same are sufllcientlydistant from the mouth of the can so that such leakage will drop intothe trough rather than into the can. Obviously the conduit or tubularelement 9 may be flexed so as to surround a container in any mannerdesired. The loop may be given any nish desired, preferably such a onethat will prevent corrosion from contact with the milkor from the water.

It is found that by using the device, which is very inexpensive toconstruct and easily cleaned, that the time required for cooling themilk and removing the `animal heat is greatly reduced, it being possiblefor the/farmer to save time in cooling, and likewise bringing his milkto the factory with a temperature sufhciently low to pass inspection.

, Having thus described my invention, it is obvious that variousimmaterial modiiications may be made in the same without departing fromthe spirit of my invention; hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of `y*parts herein shown and described or uses mentioned.
